Gunakan obyek pertukaran berjangka untuk memanggilexchange.GetMarkets()fungsi dalam sistem backtesting. Sebelum memanggil fungsi pasar manapun, GetMarkets hanya mengembalikan data pasar dari pasangan perdagangan default saat ini. Setelah memanggil fungsi pasar, ia mengembalikan data pasar dari semua varietas yang diminta. Anda dapat merujuk pada contoh uji berikut:

Peraturanexchange.GetMarkets()fungsi mengembalikan kamus dengan kunci bernama nama varietas perdagangan, dan untuk spot fix yang diformat sebagai pasangan perdagangan, misalnya:

{
    "BTC_USDT" : {...},  // The key value is the Market structure
    "LTC_USDT" : {...},  
    ...
}

Untuk bursa kontrak berjangka, karena mungkin ada beberapa kontrak untuk varietas yang sama, misalnyaBTC_USDTperdagangan pasangan, ada kontrak abadi, kontrak triwulanan, dan sebagainya.exchange.GetMarkets()fungsi mengembalikan kamus dengan nama kunci pasangan dikombinasikan dengan kode kontrak, misalnya:

{
    "BTC_USDT.swap" : {...},     // The key value is the Market structure
    "BTC_USDT.quarter" : {...}, 
    "LTC_USDT.swap" : {...},
    ...
}

• Peraturanexchange.GetMarkets()Fungsi mendukung perdagangan langsung, sistem backtesting.
• Peraturanexchange.GetMarkets()fungsi mengembalikan informasi pasar hanya untuk varietas yang diperdagangkan secara online di bursa.
• Peraturanexchange.GetMarkets()fungsi tidak mendukung kontrak opsi.
